The volcanic dome of Santa Maria, Guatemala

A historical review, of the development of the dome of Santa Maria was presented. Dome‐building began in 1922 and continued actively for a period of three years. The dome attained during this time a height of approximately 2500 feet. Since 1925 its height has remained fairly constant but its diameter is increasing by accretions brought about by intermittent activity in various parts of the edifice. This activity is occasionally accompanied by eruptions.
